Description

Technical Field

[0001] The present invention relates to the field of building structures, and in particular to a flat-floor entrance elevator building structure with a rescue passage and a rescue method. Background Art

[0002] Many multi-story residential buildings and other buildings built in the early years do not have elevators installed. Most of these old houses were built in the 1960s - 1980s of the last century, and usually have 6 - 7 floors. As time goes by, the residents of these old houses are gradually getting old, and there are problems of difficulty in going up and down stairs and inconvenient travel. Taking the elevator up and down stairs has become a strong desire and urgent need for the residents of old houses. Since the old buildings usually do not have reserved elevator shafts, installing elevators in old buildings requires building a shaft for the elevator to run and some connecting corridors. At present, the elevator installation plans for old buildings are divided into two categories: flat-floor entrance and half-floor entrance.

[0003] A typical structure of the half-floor entrance is as Figure 1 shown, including a building body and an elevator 2; the building body is provided with multiple layers of spaces from top to bottom, each layer of space is provided with a staircase public area 12 and a residential area, and the residential area is connected to the staircase public area 12 through an entrance door; on one side of the building body, there is a staircase 16 that extends upward with repeated bends, and the staircase 16 has two sections in each layer of space; in any layer of space, there is a turning platform at the intersection of the two sections of the staircase 16, the upper ends of the two sections of the staircase 16 are connected to the staircase public area 12 of the upper layer of space, and the lower ends of the two sections of the staircase 16 are connected to the staircase public area 12 of the current layer of space; the elevator 2 is installed on the side of the building body adjacent to the staircase 16, the elevator 2 has a total entrance 23 flush with the ground in the lowest layer of space, and the elevator 2 has a sub-entrance 24 in each of the remaining layers of space except the lowest layer of space, and each sub-entrance 24 is respectively connected to the turning platform in its corresponding layer of space.

[0004] In the half-floor entrance structure, the staircase can be used as an emergency rescue passage. When the elevator breaks down and people are trapped on a certain floor, the rescue personnel can reach the outside of the corresponding sub-entrance through the staircase, open the elevator landing door at this sub-entrance, and release the trapped people. However, since the elevator stops at the turning platform, after the residents enter and exit the elevator, they still have to climb half a floor (a section of the staircase), which still does not fundamentally solve the problem for the elderly and those who rely on wheelchairs to enter and exit, and there are still great difficulties in their travel.

[0005] A typical structure of the flat-floor entrance is as Figure 2As shown in the figure, it includes a building body and an elevator 2. The building body is provided with multiple floors of space from top to bottom. Each floor of space is provided with a staircase public area 12, a residential area 13, and an elevator public area 14. In the residential area 13, there is a front entrance door 131 and a rear entrance door 132. The residential area 13 is connected to the staircase public area 12 through the front entrance door 131, and the residential area 13 is connected to the elevator public area 14 through the rear entrance door 132. There is a staircase 16 extending upward on one side of the building body, and the staircase 16 is connected to the staircase public area 12 of each floor of space. The elevator 2 is installed on the side adjacent to the elevator public area 14 outside the building body. The elevator 2 has a total entrance 23 flush with the ground in the lowest floor of space, and the elevator 2 has a separate entrance 24 in each of the remaining floors of space except the lowest floor of space. Each separate entrance 24 is respectively connected to the elevator public area 14 in its corresponding floor of space.

[0006] In the flat-floor entrance structure, the front entrance door is the original entrance door, and the rear entrance door is an additional one built to adapt to the elevator, leading to the balcony or other rooms of the household. Although the flat-floor entrance has a relatively high construction cost and causes a certain change to the original housing layout, when residents go up and down the stairs, they don't need to climb the stairs, and the convenience it provides for the elderly and those who rely on wheelchairs to enter and exit is obvious. However, the biggest drawback of the flat-floor entrance structure is that there is no emergency rescue passage. When a person is trapped in the elevator, rescue personnel need to climb the staircase to reach the staircase public area of the target floor, then pass through the residential area to reach the elevator public area, open the elevator floor door at the separate entrance, release the trapped person, and then the trapped person needs to pass through the residential area to reach the staircase public area of the target floor. During the rescue process, the residential area of the household is requisitioned as an emergency rescue passage. If the household is not at home or does not agree to the passage of personnel, it is difficult to carry out the rescue operation. Therefore, the existing flat-floor entrance structure is neither convenient nor reliable and has certain safety hazards. Summary of the Invention

[0007] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a flat-floor entrance elevator building structure with a rescue passage and a rescue method. It solves the problem that the existing solutions for installing elevators in old buildings cannot take into account both convenience and safety and reliability.

[0008] The technical solution of the present invention is: a flat-floor entrance elevator building structure with a rescue passage, including a building body, an elevator, and a corridor;

[0009] There is a rooftop on the top of the building. The building has multiple floors of space from top to bottom. In each floor of space, there are a staircase public area, a residential area, and an elevator public area. In the residential area, there are a front entrance door and a rear entrance door. The residential area is connected to the staircase public area through the front entrance door, and the residential area is connected to the elevator public area through the rear entrance door. There is a rescue entrance and exit on the side wall of the building, and the rescue entrance and exit connects the outside of the building to the elevator public area of the topmost floor space of the building; There is a staircase extending upward on one side of the building, and the staircase is connected to the staircase public area of each floor of space, and the topmost end of the staircase is connected to the rooftop.

[0010] The elevator is an up-mounted machine-room elevator. There is a machine room and a maintenance entrance and exit connected to the machine room at the upper end of the elevator. There is a main entrance and exit for entering and leaving the elevator at the lower end of the elevator. There are multiple sub-entrances and exits arranged from top to bottom between the main entrance and exit and the machine room of the elevator; The elevator is installed on one side adjacent to the elevator public area outside the building. The machine room of the elevator extends above the rooftop. The sub-entrances and exits of the elevator correspond to each floor of space of the building one by one and are respectively connected to the elevator public area in the floor space where they are located;

[0011] The connecting corridor winds around and is fixedly installed outside the elevator. Its lower end is connected to the rescue entrance and exit, and its upper end is connected to the rooftop; The connecting corridor includes a first staircase section, a horizontal plank road section, and a second staircase section connected in sequence from bottom to top.

[0012] A further technical solution of the present invention is that a guardrail is fixedly installed on the side of the connecting corridor away from the elevator.

[0013] A further technical solution of the present invention is that a normally closed fire door is installed at the rescue entrance and exit.

[0014] A still further technical solution of the present invention is that there is a hole for people to go up or down at the connection between the staircase and the rooftop. There is a transition room covering the hole above the hole. There is a pedestrian entrance on the side wall surface of the transition room, and a normally closed fire door is installed at the pedestrian entrance.

[0015] The technical solution of the present invention is: A method for rescuing trapped passengers in an elevator of a flat-floor entrance elevator building, which is applied to the above-mentioned flat-floor entrance elevator building structure with a rescue passage, and is characterized in that:

[0016] When the elevator traps people in the topmost floor space of the building:

[0017] The rescue personnel climb up to the rooftop through the staircase, then go down through the connecting corridor to the rescue entrance and exit, enter the elevator public area of the topmost floor space of the building through the rescue entrance and exit, open the elevator landing door at the sub-entrance and exit, release the people trapped in the elevator, and the people then evacuate to the ground through the connecting corridor, rooftop, and staircase in sequence;

[0018] When the elevator traps people in any floor space between the topmost floor space and the bottommost floor space:

[0019] First, determine the floor where the trapped person is located. Then, the rescue personnel climb up to the rooftop through the staircase and enter the machine room through the maintenance access opening.

[0020] At this time, if the load of the elevator exceeds 50% of the rated load, manually release the brake and turn the elevator disk to the lowest floor space. Open the elevator landing door at the main entrance to release the people. The released people will be on the ground floor.

[0021] At this time, if the load of the elevator is less than 50% of the rated load, manually release the brake and turn the elevator disk to the highest floor space. Then, the rescue personnel walk down through the connecting corridor to the rescue entrance. Enter the elevator public area in the uppermost floor space of the building through the rescue entrance. Open the elevator landing door at the sub-entrance to release the people trapped in the elevator. The people then evacuate to the ground through the connecting corridor, rooftop, and staircase in sequence.

[0022] Compared with the prior art, the present invention has the following advantages: It provides a structure for installing an elevator in an old building, taking into account both the convenience of the traditional flat landing entrance scheme and the safety and reliability of the traditional half-landing entrance scheme. The convenience is reflected in that when the residents take the elevator up and down the building, they do not need to climb a section of stairs, which is convenient for the elderly and people who rely on wheelchairs to enter and exit. The safety and reliability are reflected in the design of a continuous emergency rescue passage. The emergency rescue passage does not pass through the residential areas of the users and will not affect the residents during the rescue, facilitating the rescue personnel to carry out the rescue when a person is trapped in the elevator.

A pedestrian opening 19 is provided on the side wall surface of the transition room 18, and a normally closed fire door is installed at the pedestrian opening 19.

[0037] The present invention provides a practical elevator entrapment rescue method for a flat-floor entrance elevator building. Now, the rescue method is described separately in two cases.

[0038] When the elevator traps people in the uppermost space of the building:

[0039] Rescuers climbed up to the rooftop via the stairs, then went down to the rescue entrance and exit via the corridor, entered the elevator public area on the top floor of the building through the rescue entrance and exit, opened the elevator door at the branch entrance and exit, released the people trapped in the elevator, and then evacuated to the ground via the corridor, rooftop, and stairs in turn.

[0040] When the elevator traps people in any space between the top and bottom floors:

[0041] First, the floor where the trapped person is located is determined, and then the rescue personnel climb up to the rooftop via the stairs, and then enter the machine room 21 through the maintenance entrance 22.

[0042] At this time, if the load capacity of the elevator exceeds 50% of the rated load capacity, the elevator will be manually released to the lowest level, and the elevator door at the main entrance and exit will be opened to release the people, who will then be on the ground floor.

[0043] At this time, if the load capacity of the elevator is less than 50% of the rated load capacity, the elevator is raised to the uppermost space by manually releasing the brake and turning the gear (the turning gear is a device that comes with the top-mounted machine room elevator). Rescuers then go down through the corridor to the rescue entrance and exit, enter the elevator public area on the uppermost space of the building through the rescue entrance and exit, open the elevator door at the branch entrance and exit, and release the people trapped in the elevator. The people are then evacuated to the ground in turn through the corridor, rooftop, and stairs.
